TEMPLATE HOLDER' FOR RATTERN'-('JrRADlNG` MACHINES.

industry are usually cut from stiff cardboard or the like. By means of a .pantographic vmechanism a single template may bey employed in cutting out patterns 'of different sizes all having the same relative proportions. A It is importantthat the template' shall be properly adjusted and firmly held in the adjusted position in relation to the pattern cutting mechanism. A holding device commonly used comprises a plate in combination with means for clamping ythe template in itsfadjusted position` onthe plate. f It is important that the holding apparatus be adapted for use with templates of various shapes and sizesand that the clamping meansbe adjustable thereon according to the size and lshape of the template.

The object of this invention is to provide an improved holding plate and adjustabley clamping mechanism for use in connection with a grading and pattern cutting machine.

The more particular objects-of the invention. tog-ether with means whereby the latter may be carried into effect, will best be understood from thefollowing description of V.a preferred form thereof illustrated in theaccompanying` drawings. It will be understood however' that the particular construction described and shown has vbeen choseny for purposes of exemplifcation merely, and that the invention, as defined by the claims hereunto appended, may be otherwise embodied without departure from the spirit and scope thereof.

Fig. 6 V1s an enlarged of the clamping members.

- Fig. 7 is aplanview of the slotted'transdetail view. of one parent guide plate used in marking the position for the bolt holes in the template and a j so-called sally-vamp similar to that shown inv Referring to the drawings there is shown at 10 a'holding plate embodying the invention. Thefplate is formed with a series of parallel slots or wide grooves 11, the side walls of which have horizontal flanges 12 a short distance below the top surface of the plate tocooperate with the clamping mechanism as will be hereinafter described. The grooves may or mayv not be all equally distant from each other. As shown in the drawings, the outermost two groovesat the front and rear are spaced further apart than the intermediate grooves but it is immaterial whether they are or are not all equally spaced apart.

For use in cutting certain forms of patterns, especially patterns of symmetrical form. for instance a so-called sally-vamp 13, in which there, is a longknarrow tongue 14 such as shown in detail in Fig. 8, one of the partition vportions between the grooves of the holding plate, preferably the middle one as 'shown at 15 in Fig.y 1, is formed with a series of'holes 16 to receive al screw for centering the template as wellas to aid in clamping it to the holding plate.

rEhe template will be formed with holes for Athe clamping bolts so located that when.

the' template is properly positioned von the' holding` plate, the bolt hole 26 in the tongue will be in alinement with one ofthe holes 16 in the partition 15 and the holes 25 in the body ofthe template will come directly over the middleof one of the grooves 11 in the holding plate. Means are preferably provided as will be hereinafter described for a marking plate in locating the places for' the holesv25 inthe body portion -of the pattern but inthe present'part of the description, it

already been made in proper location.

rlhe main clamping members for use in securing the body portion of the template to the' holding plate comprise a block 17, a Washer 18 and a screw 19. The block 17 is of a'suitable width and thickness to have a sliding lit in that part of thel groove 11 which is vbelow the flanges 12, 12 so that the block will now be assumed that the holes have lll may be adjusted lengthwise in any part of the groove by a sliding movement. The block may be entered into the groove at one end and then be moved beneath the flanges which will prevent the block from being pulled up out of the groove. Preferably the sides of the block are straight or otherwise shaped so that the block cannot swivel or turn.

The block 17 is formed with a central boss 21 on its upper face and with a vertical screw hole 22 extending through the boss and into the block.

rlhe washer 18 fits in the upper part of the groove and rest-s on the flanges 12, 12. It is slidable on said flanges lengthwise of the groove. lt is formed with an upwardly eX- tending boss 23. A hole extends through the washer and is adapted to be brought into alinement with the hole in the block so that the screw 19 may pass through the holes in the washer and into the block.

The template will rest upon the bosges of the several washers 18. The boss of each washer should extend slightly above the face of the holding plate so as to support the template at a slight elevation above the holding plate in order to aford a space to admit the linger of the guide of a pantagraph not shown) between the washer and the template above the surface of the plate.

The screw 19 is adapted to pass through the holes in the template and washer 18 and be screwed into the threaded hole 22 in the block 17 and will thus draw the block tightly up against the under side of the flanges 12.

Assuming that the template has been formed with the holes 25, properly located therein so that they may be alinecl with grooves in the holding plate and, if the template has a tongue 14; such as shown in the drawings, assuming that the hole 26 has been so located therein as to be brought into alinement with one of the holes 16 in the face of the holding plate, the template should then be positioned on the holding plate to bring the hole 26 into alinement with one of said holes 16 and to bring each of the holes 25 into alinement with one of the grooves 11. A plurality of blocks 17 should then be adjusted in the grooves so as to bring the holes 22 in the several blocks into alinement with the holes 25 in the template. The template will be supported on the shoulders formed by the bosses 23 of the washers 18 associated with the several blocks. Screws 19 will then be inserted through the holes 25 and through eleva-ted above the surface of the holding plate for the same reason that the boss 23 on the washer 18 is provided.

If the template does not have a tongue or is not otherwise of such symmetrical form that a portion of it must be screwed or clamped to the body of the holding` plate as well as clamped in the grooves, then there need be employed only the kind of clamping means used with the grooves.

TvVhen a symmetrical form of pattern is to be made as already described and which requires the clamping of a portion of the template to the surface of the holding plate, there is preferably employed a guide for use in locating and marking the position for the several holes in the body of the template. A guide for such a purpose is shown in Fig. 7 in association with a template. The `guide consists of a transparent plate 29 having formed therein a plurality of narrow slots 30 parallel with each other spaced at such dis-` tances apart from each other that the distance between the median line of the several slots will be equal to the distance bet-Ween the median line of two adjacent grooves 11 of the holding plate. The guide plate also has a slo-tl 32 midway between two of the slots 30. By placing the guide plate onrthe face of the template lines 31, 31 may be made on the template by means of a pointed marking tool or pencil inserted through any two of the parallel slots 30 and a line 33 may be marked through the slot 32 in the guide. After the guide is removed the holes v25 may be made anywhere along'the lines 31, and a hole 26 may be made on line 33. The holes will then be correctly spaced so that the template may then be positioned on the holding plate with bolt holes in alinement with grooves 11 in the holding plate and with hole 26 in alinement with one of the holes 16 in the holding plate.
